1. A device for use in a household appliance, the device comprising:
at least one casing configured to be placed in a treatment chamber of the household appliance, the casing comprising:
at least one output module configured to dispense at least one preparation into the treatment chamber of the household appliance and/or to trigger an output of the at least one preparation into the treatment chamber; and
at least one sensor module configured to detect sensor data characteristic of a condition of the treatment chamber of the household appliance and/or the device, wherein the at least one sensor module comprises at least one acceleration sensor,
wherein the sensor data at least partially represents data detected by the at least one acceleration sensor,
wherein the data detected by the at least one acceleration sensor at least partially represents a course of a measured acceleration over a predetermined time,
wherein the dispensing and/or triggering the output of the at least one preparation into the treatment chamber by the at least one output module is at least partially based on the data detected by the at least one acceleration sensor, and
wherein:
the data detected by the at least one acceleration sensor (i) is at least partially indicative of a load condition of the treatment chamber of the household appliance and (ii) represents a mapped curve of a measured acceleration over a predetermined time,
a controller is configured to determine the load condition of the treatment chamber by an analysis of the mapped curve, and
a harmonic sinusoidal oscillation in the mapped curve is recognized, by the output module, as being indicative of a fully loaded drum and a disharmonic sinusoidal oscillation in the mapped curve is recognized, by the output module, as being indicative of a partially loaded drum.
